> CheckpointBarrierHandler will be aware of the aligned checkpoint barrier announcement messages. Based on that, it can implement basic timeout. When arriving aligned checkpoint barrier (or it's announcement) exceeded maximum allowed `checkpointStartDelay`, it should switch to unaligned checkpoint.
> This, for the time being could be done without registering any timeout action, but a passive/static check when processing checkpoint barrier/barrier announcement. If `checkpointStartDelay` is below threshold, do nothing. If above, switch to unaligned checkpoint.
